4 weeks ago https://github.com/flutter/engine/pull/52022 has been merged. Users targeting Flutter master and beta/stable releases after (but not including) 3.27 will fail to compile if the plugin has references any v1 embedding classes.
To aid in identifying these classes here is a search query you can run in github on your repo.

Remove references to deprecated v1 Android embedding
To ensure this plugin will work with users running the next stable version of Flutter remove references to the v1 embedding.
The v1 embedding was deprecated around 6 and a half years ago. In Flutter 3.22, the Flutter tool dropped support for building v1 apps entirely. Flutter plans to delete version one of it's Android embedding in the next stable release, per https://medium.com/flutter/whats-new-in-flutter-3-22-fbde6c164fe3 (in the "Removal of v1 Android embedding" section).
When that deletion happens, any apps using plugins that still have references to the removed classes will fail to build when updating to the next stable version (probably Flutter
3.26).As a part of this deprecation, the Flutter Android team is doing community outreach by filing bugs and submitting some pull requests to update plugins to minimize the impact this removal has on the community.
Some example PRs:

3.22.If this change doesn't land, this plugin will instead be broken for all apps building on the next stable version of Flutter and beyond.
Is there a way to support both v1 and v2 embedding apps in the next stable version of Flutter?
No.
This is the PR where we are removing the deprecated engine classes: https://github.com/flutter/engine/pull/52022
